ABSTRACT:
A clutch assembly for use with a torque limiting driver. The clutch assembly comprises two relatively rotatable clutch plates, a driving plate and a camming plate, that face one another, with a plurality of rolling members housed between the two members. The driving clutch member has a face comprising a plurality of radially spaced flat areas and a plurality of recesses interposed between the flat areas, with the recesses comprising a curvilinear base area. The second camming clutch member has a face comprising a plurality of radially spaced flat areas and a plurality of opposing downwardly sloped planar surfaces interposed between said flat areas, with the planar surfaces forming an angle. The rolling members are movable from an engaged position with the clutch members to an override position. When the rolling members are in the override position, the recesses form individual housings for the rolling members that include a gap located between the rolling members and a respective curvilinear base area.
